The Metaphysics of Temporal Parts.

The metaphysics of temporal parts, also known as "perdurantism," posits that objects are extended in time similarly to how they are extended in space. According to this view, objects are made up of different "temporal parts" corresponding to different moments in time. For instance, a person is not just a single entity but comprises all their past, present, and future stages. This perspective addresses identity and change by suggesting that an object can remain the same even as its temporal parts change over time, allowing for continuity despite physical or qualitative differences.
